The palynofacies and kerogen analysis of the Upper Cretaceous units (Campanian-Maastrichtian) of the Anambra Basin, Southeastern Nigeria was carried out in the studied area. Two major palynofacies types were identified based on the abundance of particulate organic matter. The palynofacies ―A‖ is characterized by abundant phytoclasts, frequent opaqes common amorphous organic matter and carbon to...

the kazhdumi formation of the bangestan group is a well-known and important source rock in most oil-fields in the zagros basin. in order to examine productivity of this formation in southwestern iran, and to correlate petrographical and palynological data with geochemical properties, one of the best outcrops of this formation, located in tange-maghar 45 km northwest of behbahan city, was sample...

Palynological and Palynofacies analysis combined with sedimentological studies have been performed on Dalichai Formation, northeast of Semnan, in order to define its paleoenviromental interpretation. Based on petrographic studies of organic matter, three palynofacies types were recognized as PF-1, PF-2, and PF-3. PF-1 is a characteristic of proximal shelf settings or basin. This palynofacies in...

Palynostratigraphic and palynofacies analysis have been performed on hydrocarbon seep carbonate, carbonate nodule mudstone samples from the Early Cretaceous Kuhnpasset Beds in area of Wollaston Forland, Northeast Greenland. Three informal palynostratigraphic zones defined based dinoflagellate cyst occurrences. The range ?early Barremian to early Aptian age, correlate with previously These indic...

Identification of fossil material under a microscope is the basis of micropalentology. Our task is to locate and count the pieces of inertinite and vitrinite in images of sieve sampled rock. The classical watershed algorithm oversegments the objects because of their irregular shapes. In this paper we propose a method for locating multiple objects in a black and white image while accounting for ...

Palynofacies analyses of the strata penetrated by TTtex-1 Well were carried out with aim investigating stratigraphic sequence to establish palynostratigraphic zones, relative age and paleoenvironment deposition. Sixty-two ditch cutting samples within interval 2179 – 3523 m analyzed. The use acid in sample preparation for palynofacies used. result produced relatively low abundant occurrences pol...

Planktonic foraminifera and major palynomorph groups (i.e. terrestrial, marine, and amorphous organic matter) of the Campanian-Selandian strata of the Gurpi Formation were studied to evaluate the changes in the Zagros paleobasin in southwestern Iran. Planktonic foraminifera were categorized into four morphotypes according to their paleodepth, extending from Morphotype 1, comprising surface gene...

the sarcheshmeh formation is a shaly sequence of lower cretaceous age (aptian) which is deposited in koppeh-dagh sedimentary basin and conformably overlies and underlies the tirgan and sanghaneh formations respectively in the toos well # 1. lithologically, this formation has a thickness of 177m and consists mainly of marl, shale and shaly limestone. palynological studies resulted in identificat...
